For the dried tomatoes, preheat the oven to 90°C (top and bottom heat).
Halve the cocktail tomatoes – cut large tomatoes into slices. Marinate with salt and herbs (if you like) and let them dry in the oven with the cut surface upwards for 4-6 hours.
Keep checking until desired consistency is reached (varies by size of tomatoes).
The dried tomatoes will keep for a few days in the refrigerator, it is best to store them in a sealable container, covered with a good olive oil.
